.To all colto/ln may concern."

Be it known that l, CHARLES Gr. Ross, a citizen el tbe United States, residing at Chicago, in the connty'of Cool: and State of llllinois, have invented. certain new and useful Improvements in Bumpers for Motor vVehicles, of which the following is a specitication.

lvly invention relates to bumpers for motor vehicles.

'Bumpers of this type comprise an impact section and a supporting section therefor, tbe latter being secured to the frame members of the motor vehicle. It is difficult to manufacture tbe impact and supporting sections oit tbe bumper 4freni one continuous piece of metal.' Furthermore, it is desirable to .malte tbe impact section off tbe bumper of,

considerable widti so that. the likelihood of bumpers on other vehicles, in case of collision,

slipping over Aor under tbe impact section will be minimized, consequently tbe impact section ireqnently, comprises a plurality ed parallelly extending bars. The several parts f ot tbe bumper are ordinarily lmade of standard resilient steel bar stock. llt bas become common practice, therefore, to make the impact section of the bumper separate from the supporting means therefor which, obviously necessitiates some foi-1n of connection between the ends of the impact section and the adjacent ends of the supporting means. One of tbe objects et my invention is to provide a 'form of connection between the parts aforesaid which will be of very simple construction,:inexpensive to manufacture, easy to assemble or repair, pleasing in appearance and which will be strong, durable and reliable in operation.

lily invention contemplates the provision or a slotted tubular member into which the ends of the bars to be connected may be inserted; and, .a further object of my invention is to provide means preferably within tbe tubular member for securely holding the bars against movement in the direction of their length relative to the tubular member.

Another object of my invention is4 tbe ,revision ont means whereby the ends of the bars disposed within the tubular meinber-may be securely clamped toffetber and to said member thereby securely holding them against movement in a vertical direction relative to each other and to said mem The invention consists in the novel constructions, arrangements and devices to be hereinafter described and claimed for can rying out the above stated objects and such other objects as vvill appeal from tbe o1- lowing description of certain preferred e1nbodiments illustrated in the accompanying drawings, wherein- Fig. lis a plan view and Fig. 2 is a front elevational view of a. bumper embodying tbe principles of my invention;

Fig. 3 is a sectional view, on an enlarged scale, taken on the line 3-3 4of Fig. 2;

Fig. 4 is a pers ective View, on a further enlarged scale, oli) one form of means employed for securing the bumper Abars within the tubular connecting members;

l'iike characters oi reference designate like parts in the several views.

4Referring lirst to Figs. 1 and 2, the bumper therein shown includes a ytransversely extending resilient supporting bar 12 which may be mounted on the ends of the respective longitudinally extending channel members of the chassis frame (not shown) by any suitable means,or example, L-sbaped bracket members 13. Two resilient impact members 14 placed end to end are disposed in a plane above that of the supportinor member 12. Two resilient impact mem ers 15; also placed end to end are disposed in a plane below that of the sup porting member ,12. The outer ends 14a and l5 et' the two 'sets of impact members and the respective outer ends l2 of the supporting member 12 are preferably formed so that they are in substantial alignment, said adjacent ends being connected by a. device designated generally by the reference numeral 16. l resilient bar 17 of elliptical lee llll

they nre in substantie-.l sliqnment. A. noem ber 19 is provided on its upper and lower ends with laterally extending perornted eers 2li. Devices i6 entend, respectively, through the sets of eers 20 of the connecting member i9 and in conjunction. 'with the member 19 complete the connection betweerr tubular inem the respective inner ends of the .impact bere lil and l5 and the. adjacent ends of the bor 1I.

Each of the aforesaid members 16 in cludes a. vertically disposed tubular member 21 which is provided with n vertically extending slot 22 and externally treaded on its upper and lower ends for cap nuts 23. In that. form my invention shown in Figs. l to 5, inclusive, pairs of complemenfrespectively, are mounted on the inner :n outer ends of the impact bars le and l5, the outer ends of the su porting bnr 'l2 :ind the ends of the bar 11. The members 2i nre recessed :it 24C, Fig. 5, on their adjacent teces,.thus providing e slot 2e, to receive the end of the bar, the two members being' secured together and on the bar by any suitable means, for example, by n. rivet rlie members 24 are shaped externally to iit snugly Within the respective bores 21- of the tubular meinbers. The members 24 are oi" u length suiiicient to provide houd and foot portions. 24.

The assembly of the various part-s or" the bumper will be clearly understood from the foregoing description fmdthe following specitie description of the manner in which the outer ends `oi" the impact bars le and l5 und the supporting bor l2- nreconnect-ed. @ne of the nuts is threaded onto one end, for exemple, the lower end of the tubular member 2l. The outer end of the bnr l5, with its members 24; secured thereto, is passed down through the sist 22, the loner ends oi the nien'ibers resting on the nut 2251.I The outer end of the bor v12, 'with its members let vsecured tl'iei'eto, is then slipped througl'i the slot 22, the lower ends of its members resting' on the top end of the members carried by the ber 15. The out-er end of the bar le, with its members 24 secured thereto, is then passed through the slot 29, the lower end ot' its members resting on the top end of the members carried by the bei i9.. The other nut 23 is then threaded onto the upper end of the tubular member. lt will be noted that the portions 2e of the inen'ibers 2li 1lirovide spacingl ineens bet-Ween 'the bars lli sind l2 and the bers i2' sind l5. lt will also be noted that the three members 2l com, eteiy lill the '.f. En this construction the ends of the bers carry laterally projecting pins 27, j ends of seid bars are adapted to be ed down through the slot 22 with s f2? lyinff Within the d spacing iy disposed member 28, Fig. within the tubi the bars. Retaining r the spacing member Le disposed between the e spective pins 527 and slot 22.' The in ner sides of the resi; one being shown) are concevely' and the retaining rode 9e .ere ci: such. .eiiggth that when the nuts 30 are home they will tend to force the ends of the rods 29 tightly against the sides of the 27 thereby preventing outward movement of the bars 26 in the direction o their length rel-` ative to the tubular member 2l, Rods may be employed in conjunction with the rods Q9 so as to hold mo 3 securely the bars against movement reliance to the tubular extend throu4 bers 28, bei mes .of the and between nuts 30, {only member. The parte are so arranged that the bars 26 are securely clamped between the nuts 30 thereby preventing any relative movement of the bars in s ve il. direction.

In that form of' invention shown in Figs. 9 and l0 the bers 3l ere formed on theirV ends with enlarged portions 31u. pertured S13-:icing members 32 ere disposed Within the tubuler member between the bars. Retaining roL s sin ier to die reds 29, extend through the amber or members being dispos cs. iront of the projecting portions Sila of bers.

ln all forms ofi my ine 1 l the impact bars and the supporting c ere securelyJ held against movement in 'Lne direction o'ii their length relative to 'the connecting de vices 16. The ends of the bers are also se curely clamped egninst verticel movement relative to eac cl3-berend to thetubular conneet-ing membe ,by the clamping I: The construction. is very simple und i" pensive to manufacture. The several i of the bumper may be readily and comen iently assembled. Should one of the impact bars, jor example, or the supporting ber 12 receive such n severe bienvv that it will not return to its originel shape, the particular peri; may be readily replaced by u good part, the only tool needed being c. f y

common Wrench. Since the means for se# clam ing said devices together within said mero er.
